我們廣泛的氣動繼電器系列適用于多種控制應用：正偏壓繼電器，正偏壓和負偏壓繼電器，無級可調比率繼電器，可逆繼電器，平均和計算繼電器，高低壓選擇器以及高低壓限制繼電器。
偏置繼電器
正偏置和負偏置繼電器設計用于需要輸出壓力為受控輸入信號加上或減去固定偏置的總和的應用。飛兆半導體的氣動偏壓繼電器產品線包括正偏壓繼電器，例如型號15,85D和1500A以及處理正偏壓和負偏壓功能的繼電器，如14型。
反向繼電器
反向繼電器設計用于要求輸出等于手動預設彈簧負載減去可變信號壓力的應用。這些高質量的設備，例如25型和2500A型，結合了的靈敏度和異常高的流量。這些飛兆逆變氣動繼電器非常適用于各種精密控制應用，包括將直動閥轉換為反向動作，控制來自單個變送器的相反作用閥，以及緩沖氣缸負載。
可調比率繼電器
飛兆半導體的21型是一款可調比率氣動繼電器，輸出壓力與信號壓力的比值是無限可調的。調整范圍允許信號放大1:30或比例調整旋鈕的旋轉信號減少30：1。 21D型可提供輸入和輸出可調偏置。zui大輸入偏壓為3 psig，zui大輸出偏壓為9 psig。
氣動計算繼電器
22型氣動計算繼電器專為設計用于執行多種專業功能（包括平均，差分，反相和積算）的高度多功能控制閥而設計，是一款多功能的飛兆半導體產品。這種高質量的設備可提供多達四個輸入以及大范圍的正負偏置，可提供多種配置以滿足大多數應用需求。
快動作繼電器
24型快速動作繼電器是一款高精度差動繼電器，具有快動式開關功能。當信號等于或大于設定值時，設備的輸出將會提供壓力。信號壓力必須低于設定值才能將輸出恢復為零。這款氣動繼電器的接近零節流和先導分級功能可以在您的應用中實現真正的快速切換。
選擇繼電器
90型低壓和91型高壓選擇繼電器設計用于選擇兩個信號壓力中較低或較高的壓力，為控制裝置提供持續的輸出壓力。 90和91型推薦用于關鍵應用中的死端或低流量服務，例如需要自動監控信號壓力的控制回路。

Relays

Our extensive line of pneumatic relays serves a multitude of control applications: positive biasing relays, positive and negative biasing relays, infiniy adjustable ratio relays, reversing relays, averaging and computing relays, high and low pressure selectors, and high and low pressure limiting relays.

• Biasing Relays

  

  Positive and Negative Bias Relays are designed for applications that require an output pressure that is the sum of a controlled input signal plus or minus a fixed bias. Fairchild's line up of biasing pneumatic relay products includes both positive biasing relays, such as the Models 15, 85D and 1500A and relays that handle both positive and negative biasing functions such as the Model 14.

• Reversing Relays

  

  Reversing Relays are designed for applications requiring an output that equals a manually preset spring load minus a variable signal pressure. These high quality units, such as the Model 25 and Model 2500A, combine excellent sensitivity with unusually high flow capacity. These Fairchild reversing pneumatic relays are ideally suited for a variety of precision control applications, including converting direct acting valves to reverse action, controlling opposite acting valves from a single transmitter, and cushioning cylinder loads.

• Adjustable Ratio Relay

  

  Fairchild's Model 21 is an Adjustable Ratio Pneumatic Relay, whereby the ratio of output pressure to signal pressure is infiniy adjustable. The adjustment range permits signal amplification of 1:30 or signal reduction of 30:1 by rotation of the ratio adjustment knob. The Model 21D is available with both input and output adjustable bias. Maximum input bias is 3 psig, with a maximum output bias of 9 psig.

• Pneumatic Computing Relay

  

  Designed for highly versatile control valve designed to perform a number of specialized functions, including averaging, differential, inverting, and totalizing, the Model 22 Pneumatic Computing Relay is a versatile Fairchild product. This high quality unit, which offers up to four inputs as well as positive and negative biasing over a broad range, is available in several configurations to meet most application requirements.

• Snap Acting Relay

  

  The Model 24 Snap Acting Relay is a highly accurate differential relay with snap-acting switching. The output of the unit will go to supply pressure when the signal is equal to or greater than the setpoint. The signal pressure must fall below the set point to return the output to zero. This pneumatic relay's Near Zero Throttling and Pilot Staging result in true snap-action in your application.

• Selector Relays

  

  The Model 90 Low Pressure and Model 91 High Pressure Selector Relays are designed to select the lower or higher of two signal pressures to provide a continuous output pressure to a control device. The Model 90 and 91 are recommended for dead end or low flow service in critical applications such as control loops requiring precise, automatic monitoring of signal pressures.
